IMPROVEMENT IN FIRE-EXTINGUISHERS.

Specification forming part of Letters Patent No. 145,405, dated December9, 1873; application tiled February 27, 1873.

CASE B.

To all whom it may concern.;

Be it known that I, WEAR L. DRAKE, of Evanston, in the county of Cookand State of Illinois, have invented certain new and useful.

Improvements in Fire-Extinguishers, of which improvements the followingis a full, clear, and exact description, which will enable othersskilled in the 'art to which my invention apperta-ins to make and usethe same, reference being had to the accompanying` drawing forming apart of this specifica-tion, and in which- Figure l represents avertical central longitudinal section of a fire-extinguisher providedwith my improvements; and Fig. 2, a horizontal cross-section of the samein the plane ofthe line x x in Fig. l.

Like letters of referei'ice indicate like parts.

My invention relates to that class ot' lire-extinguishers renderedoperative by being tilted, and from which water is discharged by meansof gas generated in the extinguishers. Extinguishers of this class havebeen supported on trunnions resting on carriages or suitable frames; Thehose is connected to this class ot extinguishers in such a manner thatthe attachment cannot be properly made until after the extinguisher hasbeen tilted. The object yof my invention is to render the hose capableof being attached at any time; and my invention consists in the meanshereinafter particularly described and specified, and employed for thepurpose of accomplishing the object above set forth.

In the drawing, A represents an extinguisher of the class referred to. Bis a spunwheel rigidly attached to the extinguisher. C is a hollowtrunnion. D is a pipe communicating with the trunnion C and with thereservoir of the extinguisher. E represents the carriage orsupporting-frame. F is also a spur-wheel engaging the wheel B, andrigidly attached to the crank-shaft G, having a bearing on the frame E.

The trunnion C may continue entirely through the extinguisher, as shown,or each trunnion may be separate and communicate with a pipe, D, or onlyone trunnion may be hollow. The pipe D should continue to, or nearly to,the head of the extinguisher.

It will be observed from the foregoing description that `theextinguisher may be readily tilted by means of the crank G, and that thehose may be attached to the hollow trunnion at any time, and withoutbeing disarran ged durin g the operation ot' inverting the extinguisher.

All, or nearly all, the contents ot' the extinguisher will be dischargedthrough the hollow trunnion, according to the position of the latterandto the length of the pipe D. I deem it preferable to arrange thetrunnions at, or nearly at, the center ot' the extinguisher, as shown,so that the latter will be as evenly balanced as may be practicable; butthis ar rangement is not absolutely essential, except l for the purposereferred to; nor is the employment of a pipe, l), necessary, except forthe purpose of discharging all, or nearly all, the contents of thereservoir, when the hollow trunnion is not arranged at or near the head0f the extinguisher.

Any gearing suitable for the purpose of fa cilitating the operation oftilting' the extinguisher may be employed for that purpose, or theextinguisher may be tilted by a pressure exerted by the hand.

Having thus described my invention, what I claim as new, and desire tosecure byLetters Patent, is-

A tiltiu g lire-extinguisher provided with one or more hollow trunnions,substantially as and for the purposes specified.
